From BNA Inc. Criminal Law Reporter: The Ninth Circuit says federal agents did not violate the Fourth Amendment when they copied a voluminous computer directory holding drug-testing records of hundreds of professional athletes as they executed a search warrant that authorized the seizure of such records relating to only a handful of Major League Baseball players. The ruling has broader implications for the confidentiality of all sorts of personal records maintained in a database when law enforcement officials obtain a search warrant for only some of them.
